Recessed lights burning out

My daylite basement has nine Juno 6" cans on one three way circuit. I have never been able to get decent life from any type of lamp that I've used. Both standard lamps and Halogens burn out after only very short usage. They are IC rated cans, but there is no insulation in the joist space. Similar cans on the main floor work just fine, with decent lamp life. Right now I've put plain 60W bulbs in and nothing has failed in the last couple of weeks, but they look terrible. Any ideas?

Similar is not the same...somewhere in the fixture is usually a sticker indicating what are the acceptable bulbs. Are you using one that is acceptable?

An IC rated box usually has a thermostat in it that will shut the thing down if it gets too hot. If they're defective, the opening and closing would be like you sitting flicking the switch on and off for an extended time - that can cause a bulb to fail quickly. Same thing about the switch on the wall, if there's a loose connection somewhere either at the switch or somewhere in the string supplying power. If they're all on the same breaker...could be the breaker, or the screw attaching the power leads to it or the neutral bar.

I'd look for a loose connection either at the switch or the supply if the bulbs you are using are on the accepted list.

The CF lights don't last as long in a can, but they do work for a couple years.

PS: I just got my first LED light
It's a 7 watt Par20 light and even though it's only 200 lumen's, it's actually about the same amount of light since the CF bulbs I am using aren't set up with reflectors.
